 |This is not a question for the bugs list.

 |Write to help@python.org or use the newsgroup for help.  I don't know
 |offhand what the answer is to your question; I suspect that the answer
 |is in the Tcl/Tk man page for the bind command though.

My fault.  I should have rephrased the question into a statement.  Tkinter
does not provide symbol defines for event.state values (%s keyword in Tcl).
Tcl doesn't either, but it would be useful if Tkinter did.

This is a small enhancement request rather than a hard bug, but I thought
the submission form was for probably applicable for both.

Thanks,

Randall
